Y Chromosome IV: Recombination Suppression

Last time we discussed the discovery of “evolutionary strata” on the human X chromosome – there are distinct blocks on the X that stopped recombining with their Y-homologs at different times causing the Y chromosome’s genes to appear scrambled in order. How can this happen?

Y Chromosome III: Evolutionary Strata!

Last time we discussed the composition of the human Y chromosome. Today we will examine one of the classes described by Skaletsky et al. (2003), the X-degenerate class, in more detail. The primary model for Y-chromosome degeneration is a decrease in X-Y recombination. Because and X and Y chromosomes are not kept the same by […]

Y Chromosome II: What Is Its Structure?

Hi all! My name is Kele Cable and I’m an undergrad majoring in biology. I recently started my own science blog and Razib has offered me the opportunity to cross-post here. I am currently writing a blog series that focuses on the topic of the Y chromsome (on which I wrote a paper this last […]
